This feature is useful with inline assembly and macros. For example, a macro
that reads a CRTC register may be written like this:
#define wr(idx) (__AX__=(idx),asm("\tsta\t$2000\n\tlda\t$2000\n\tldx\t#$00"),__AX__)
An obvious problem here is that macro definitions may not use more than one
line.

asm("\tsta\t$2000\n\tlda\t$2000\n\tldx\t#$00"), \

(The example is rather stupid, since the text in text.s does not use the
correct character set for the target machine - conversion is usually done
by the compiler. However, we will ignore that here.)
We assume that the target file should be named "hello", and the target
system is the C64.
